Metallic Bonding Concepts

Front

Why are metals good conductors of heat and electricity

Back

They have free (delocalised) electrons which carry the energy through the metal.

Front

Why are metals malleable?

Back

Layers in structure can slide over each other

Front

What elements are used in metallic bonding?

Back

Metals only

Front

Describe the structure of metals

Back

A giant structure of atoms in a regular pattern.

Front

Definition of metallic bond

Back

A strong electrostatic attraction between the positive ions and the delocalised electrons between them

Front

Definition of alloy

Back

A mixture of two or more elements, one of which is a metal

Front

Reason for high melting points of metals

Back

Metallic bonds are very strong

Front

Why are alloys harder than the pure metal?

Back

The different sized atoms disrupt the layers making it harder for them to slide.
